Particle dynamics around an electrically charged Kiselev black hole embedded in quintessence

open access: yesNuclear Physics B
We introduce and study a new solution describing a static, spherically symmetric and electrically charged black hole embedded in a charged quintessence fluid, which corresponds to an electric generalization of the Kiselev geometry.

Exact solutions of conformable fractional differential equations

open access: yesResults in Physics, 2021
This article is about to formulate exact solutions of the time fractional Dodd-Bullough-Mikhailov (DBM) equation, Sinh-Gordon equation and Liouville equation by utilizing simplest equation method (SEM) in conformable fractional derivative (CFD) sense ...

Exact Solutions with w - modes

open access: yes, 2001
An explicit necessary condition for the occurrence of resonance scattering of axial gravitational waves, along with the internal trapping of null geodesics, is proposed for static spherically symmetric perfect fluid solutions to Einstein's equations ...

New Exact Solutions of Quadratic Curvature Gravity [PDF]

open access: yes, 2012
It is a known fact that the Kerr-Schild type solutions in general relativity satisfy both exact and linearized Einstein field equations. We show that this property remains valid also for a special class of the Kerr-Schild metrics in arbitrary dimensions ...

Heat transfer analysis of Rabinowitsch fluid flow due to metachronal wave of cilia

open access: yesResults in Physics, 2015
The present investigation concerns with the mechanical properties of a Rabinowitsch fluid model and the effects of thermal conductivity over it. Flow is considered to be occurring due to metachronal wave produced as a result of constant beating of cilia ...

Exact dark energy star solutions

open access: yes, 2011
Adopting the phantom (ghost) scalar field description of dark energy, we construct a general class of exact interior solutions describing mixed relativistic stars containing both ordinary matter and dark energy in different proportions.

Exact Solutions to the Sine-Gordon Equation [PDF]

open access: yes, 2010
A systematic method is presented to provide various equivalent solution formulas for exact solutions to the sine-Gordon equation. Such solutions are analytic in the spatial variable $x$ and the temporal variable $t,$ and they are exponentially asymptotic

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

The exact cosmological solutions for phantom fields

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2011
The application of the method of super-potential to solution of the problems of cosmology with phantom fields is examined. The classes of exact solutions are found and the periods of time with the predominance of dark energy are established.
